An AMD allows an adult patient to make instructions in advance for situations where they are mentally capable of deciding on a life-sustaining treatment (“LST”), following in-depth discussions with family members and healthcare professionals. The adult may refuse one or more life-sustaining treatments. The model AMD forms can be in paper form or in electronic form (when the designated electronic system is in operation).
In Hong Kong, a mentally competent patient aged 18 and above can make an AMD. This is for the patient to explicitly express their wish to refuse specified life-sustaining treatment (LST) in pre-specified conditions when they are in an end-stage condition and mentally incapable of making health care decisions. In the event of the patient’s health deteriorating, healthcare professionals will adhere to the patient’s AMD regarding the withholding or withdrawal of pertinent LSTs, provided that the specified preconditions in the AMD are met.
The Hong Kong Government introduced the Advance Decision on Life-sustaining Treatment Ordinance (“the Ordinance”) and it will be effective in May 2026. After legislation, the new AMD legislation grants statutory power to AMDs, specifying their making, revocation, scope, and definitions within the law. Any deliberate obstruction of the execution of an AMD will result in potential criminal liability.

Do-Not-Attempt Cardiopulmonary Resuscitation (DNACPR)
To facilitate adherence to instructions in an AMD in situations demanding immediate decisions without the presence of medical professionals (e.g. outside the hospital setting), registered medical practitioners (RMPs ) may make AMD-based DNACPR orders for AMD makers who have specified in their underlying AMDs a refusal of cardiopulmonary resuscitation (CPR). AMD-based DNACPR orders instruct not to perform CPR on the subject person under applicable circumstances when that person is in a cardiopulmonary arrest.
Given that minors and adults who are mentally incapable of deciding on LSTs cannot make AMDs, RMPs may make a non-AMD-based DNACPR order for them if a consensus is reached among the patient’s attending RMPs and family members that CPR would not be in the patient’s best interests. A responsible person (e.g. family members) has to agree with the decision and co-sign the non-AMD-based DNACPR order.
DNACPR orders must be made in writing using a prescribed form for easy identification and verification. Otherwise, the orders will be considered invalid.
